Check the horizontal output section circuit. It sounds that the LOT {Line Output Transformer} has damaged.

I have an RCA DLP tv model HP50LPW52. the sound was there with no picture. since it is 5 years old I replaced the lamp for the first time. got it all hooked up, turned it on and the tv slowly came on....


That is your Color Wheel that is bad. I wish you would have posted the problem before buying a lamp. I would have told you to treat yourself to a new set instead of putting good money into a DLP set that is 5 years old.

That, I would guess, is a decoupling problem in the decoding section of the audio stage, or a poor connection in the audio section. Unfortunately a service manual and engineer will be required to find the problem
Hope that helps.

High pitched squeal


Hi...

Does the squeal come from the TV cabinet or the speaker?
If from the cabinet , it's most likely the Horizontal high-voltage section of the set.
Find someone that's good with hand tools,unplug the set from the wall outlet, let it sit for a good 30 minutes.
have someone open up the back of the set and dust out and vacuum out any dust from inside the set.
Put back together and try it out.

New High Pitch sound


If the sound is from the compressor, the unit is likely under warranty...generally 5 years.  If the unit is frozen up and the sound is from a fan that is hitting ice, defrost the unit completely.  Other fans in the unit could also be squealing.  You'll have to be a detective.

High pitched squeal from TV


Get a small wood/plastic stick and touch the different coils/transformers to see which one is the cause. Replace part or if the part doesn't run hot, use a small amount of hot melt to quiet. Don't completely encapsulate in glue, don't want to create any hazards.
